Betty’s monthly income is $550 and her savings is $250. Find savings to expenses ratio.

Savings to expenses ratio is 5:6

Solution

Betty's Income = $550

Savings = $250

Expenses = 550 - 250 = 300

∴ savings to expenses ratio = 250:300 = 5:6

Savings = $250

Expenses = 550 - 250 = 300

∴ savings to expenses ratio = 250:300 = 5:6

2

Out of 112 students in a class, 40 are boys. Find boys to girls ratio.

Boys to girls ratio is 5:9

Solution

Total Number of students = 112

boys = 40

girls = 112 - 40 = 72

∴ Boys to girls ratio = 40:72 = 5:9

boys = 40

girls = 112 - 40 = 72

∴ Boys to girls ratio = 40:72 = 5:9

3

Length and breadth of a rectangular field are 88 feet and 32 feet respectively. Find the ratio of length to breadth of the field.

Length to breadth ratio is 11:4

Solution

Length of a rectangular field = 88

breadth of a rectangular field = 32

∴ Length to breadth ratio = 88:32 = 11:4

breadth of a rectangular field = 32

∴ Length to breadth ratio = 88:32 = 11:4

Solution

Total Number of students = 38

Number of students prefer football = 8

Number of students prefer baseball = 12

Number of students prefer tennis =38 - (8 + 12) = 18

∴ Number of students who prefer football to number of students who prefer tennis ratio = 8:18 = 4:9

Number of students prefer football = 8

Number of students prefer baseball = 12

Number of students prefer tennis =38 - (8 + 12) = 18

∴ Number of students who prefer football to number of students who prefer tennis ratio = 8:18 = 4:9
